The T1 Complete Fuel Solution for the R35 Nissan GT-R comes with all the necessary parts required for install, but there are specialty tools which will make installation much easier. Installation is HIGHLY recommended to be performed by a qualified mechanic. Before any of the required work is started make sure the car has been given adequate time to cool and the battery is disconnected.
If you have purchased the system which includes the in-tank portions of the system, please see attached file for installation instructions. There are some minor differences between the T1 kit and the kit depicted in the instructions, but they serve as a great guide. Please note that the T1 version will only utilize a single pump so you will have an empty fuel pump spot in the hanger. The hanger is assembled, minus the pump, with an inlet filter so it's very clear which side the pump should be installed on.
We offer the GT1R BPC HARNESS in two versions, one that mounts the BPC in the trunk, and one that mounts the BPC under the passenger seat carpet. If mounting the BPC in the trunk, there are a couple ways it can be done between simply mounting it to the floor, or on the rear divider. Mounting it under the passenger seat takes a bit of creativity, but works very well. With the carpet lifted and the main foam support out, you can see the BPC fits nicely:
It can be secured to the floor here with something like 3M Dual Lock Reclosable Fastener. You will need to trim the foam to suit, and your end product will look something like this:
Once this is done the carpet will sit down just as it did stock and the BPC is completely hidden!
Notable differences from the instructions are as follows:
1) When you get to Step 9 of the instructions please note there are a couple configurations offered. If you purchased the GT1R BPC HARNESS, FPS1100 kit, and our hanger together we have terminated the fuel pump harness for you entirely, and have included pigtail connectors for the fuel level and temperature located on the second connector. If you have chosen to do your own wiring, you will have two matching six-pin connector kits (terminals and cavity plugs not pictured below but are provided) and either one or two pigtails for the fuel pump(s) itself, where the AMS kit has two fully terminated harnesses.
The connectors with the grey locks have seals internally and should be used on the outside of the hanger. The other two connectors will be your internal connectors and need the red locks removed in order to mate with the bulkhead. The red locks can be removed easily by depressing the lock as seen below and pulling out:
For a single pump, the fuel pump pigtail will be terminated to one of the two internal six pin connectors, and you will use two cavity plugs to occupy the two vacant holes on the external connector. For a dual pump setup, one more wire will be terminated and only one cavity plug will be used. More details on this can be found at the bottom of this installation manual along with the other wiring information.
1) When you get to Step 19 of the instructions please note: There is an internal filter that needs to be removed:
Once the filter is removed you will also be drilling an additional hole in the return jet. A 7/64" bit can be used for this, and you can see where to drill the hole, and a completed return jet below:
1) When you get to Step 27 of the instructions please note there are two different wiring jobs to perform, depending on if you use a single or dual brushless pump setup. If you are only using a single pump, the two bulkhead connectors will be terminated as follows:
If you are using dual pumps, the bulkheads will be terminated in this manner:
If you have purchased either our single or dual pump plug and play harness and hanger assembly together, the internal pump wiring has been nearly all completed for you. You will simply need to connect the OEM fuel temperature, level, and grounds to the color coded wires show in the tables above using the provided butt connectors and shrink.
You will need to cut/depin the OEM wiring on the external connector for fuel temp/level to be terminated into the new hanger mating connector. The open cavities should be plugged on the external connectors with the provided plugs. Internally, the fuel temperature wiring is long enough to cut the OEM terminals off and crimp the provided ones on, but you will likely need to extend the fuel level wiring.
If you have opted for our PNP harness, an internal and an external pigtail have been provided, and you will simply cut your fuel temp and level wiring to length, use the supplied butt connectors, and shrink to finish out the harness.
The completed internal wiring should look something like this once done:
It's not extremely clear how the pump/pre-filter assembly go together in the directions below, but this picture below shows you the order with which the components are assembled:
The billet aluminum grommet support will go on the pump outlet, followed by the actual grommet itself. The two teflon seals will go on the pump inlet, followed by the o-ring which seals the pump to the filter inlet housing. With this done simply click on the pre-pump filter to the black housing.
Once you have completed Step 57 you are officially done with the internal pump and hanger setup!
If you are using a MoTeC M150 ECU, we have created a basic instruction document to assist with setup as well:
